After 10 months we are averaging about 15 euro per week ESB costs for the geo with on demand hotwater. But we did put in tighter loops in our UFH in order to reduce the running temp, therefore reducing the cost to run it.
15 euro/wk means nothing in regard to the topic. Do you never watch TV, boil the kettle, use an electric oven, switch on lights etc. ?
Unless you are talking about 15 euro a week JUST for the UFH/Geothermal....in which case that's a whole lot of money !!!!
Pique318, if you read Yop's post correctly you'll note that he did specify that the cost was for Geo. You can see from previous posts that the house is 2100 sq ft.
Are you serious when you say 15 Euro a week is expensive for water and space heating? That's less that 800 a year assuming the current level of usage. Bord Gain standing change is over 300 before you use any gas! Previous posters have reported gas bills of over 400 per two months for similar and smaller houses.

Yop,
Just a question on the loops, How far apart did you put them.
Also, What is the max longth of you zones.
I am looking at Unipipe and possibly vertical trial hole running a NIBE heat pump.
I was mailing you before on these issues.
Thanks
If I had know the extra costs and hassle of the 1m horizontal bed (cost of digger, sand for above & below pipes - 3 loads), I would have given more consideration to the vertical borehole (the grant is more and it would be more self contained which might outweight the drilling cost).
We have solar installed and are not to happy with the output/performace so far. They are supplied from a reputable supplier who has been in the business for several years. The amount they contribute to heat is not worth the expense, as pay back is to long. I heard all the talk about how much they do before we installed them. DHW heat is not the highest bill, space heating is. Solar does not contribute much during the winter months and heaps (hopefully) during the summer. We also have a pellet boiler and are happy with that. But solar, hmmmmm. Optimistic
Yop/Mickeyg
We've just moved into our selfbuild in galway, t/f, 300 sqmt bungalow, with lots of insulation and alu-clad timber windows. We put in a heliotherm geo-pump with gas ground pipes to heat domestic water, UFH downstairs and wall heating upstairs (both Gabotherm). Everything is working great, but given all the insulation, the heating isn't really tested/required this time of year. Climate control in tuam did all the heating and their engineer certainly knew his stuff. It looks like the same company Yop went with. The fact that its running well for you gives me great peace of mind as I'll have to monitor the cost/efficiency thro the coming winter before giving it the final thumbs up.
So, sparki74 and mickeyg, I wouldn't be put off the geothermal at all, it's more expensive to start with but the grant helps there. If I had know the extra costs and hassle of the 1m horizontal bed (cost of digger, sand for above & below pipes - 3 loads), I would have given more consideration to the vertical borehole (the grant is more and it would be more self contained which might outweight the drilling cost).
